74HCT193 PDF – 4-bit Binary Up/Down Counter

Part Number : 74HCT193

Function : Presettable synchronous 4-bit binary up/down counter

Package : DIP, SO, SSOP, TSSOP 16 Pin Type

Manufacturers : NXP Semiconductors.

Pinouts :
74HCT193 datasheet

Description :

The 74HC193, 74HCT193 is a 4-bit synchronous binary up/down counter. Separate up/down clocks, CPU and CPD respectively, simplify operation. The outputs change state synchronously with the LOW-to-HIGH transition ofeither clock input.

If the CPU clock is pulsed while CPD is held HIGH, the device will count up. If the CPD clock is pulsed while CPU is held HIGH, the device will count down. Only one clock input can be held HIGH at any time to guarantee predictable behavior.

Features and benefits

1. Input levels:
(1) For 74HC193: CMOS level
(2) For 74HCT193: TTL level

2. Synchronous reversible 4-bit binary counting

3. Asynchronous parallel load

4. Asynchronous reset

5. Expandable without external logic

6. Complies with JEDEC standard no. 7A

SAF7741 datasheet

Description :

The SAF7741 is a combined Intermediate-Frequency (IF) car radio and audio Digital
Signal Processor (DSP) with several powerful cores integrated onto a single device. It
combines analog IF input, digital radio and audio processing, sample-rate converters and
digital and analog audio output to enhance listening clarity and noise suppression while
reducing multipath channel effect.


1. Dual/Single, low-IF car radio and audio software DSP
2. Low-IF concept for high performance at reduced system cost
3. New PDC including IQC
4. Dedicated dual digital radio interface to co-processors for HD Radio and DRM
5. Supports co-processors for any digital radio standard such as DAB/DMB and SDARS


The SAF7741HV is designed for use in high-performance car radio systems.
