Philips 74HC299
The 74HC/HCT299 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. The type of operation is determined by the mode select inputs (S0 and S1), as shown in the mode select table.| Part No. | 74HC299 |

FEATURES
● Multiplexed inputs/outputs provide improved bit density● Four operating modes: – shift left – shift right – hold (store) – load data
● Operates with output enable or at high-impedance OFF-state (Z)
● 3-state outputs drive bus lines directly
● Can be cascaded for n-bits word length
● Output capability: bus driver (parallel I/Os), standard (serial outputs)
● ICC category: MSI
GENERAL DESCRIPTION
7A. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns 74HC/HCT299 The 74HC/HCT299 contain eight edge-triggered D-type flip-flops and the interstage logic necessary to perform synchronous shift-right, shift-left, parallel load and hold operations. All flip-flop outputs have 3-state buffers to separate these outputs (I/O0 to I/O7) such, that they can serve as data inputs in the parallel load mode. The serial outputs (Q0 and Q7) are used for expansion in serial shifting of longer words. A LOW signal on the asynchronous master reset input (MR) overrides the Sn and clock (CP) inputs and resets the flip-flops.
